Application. filed. Detober 17, 1921. Serial No 508,185.

To all whom it may concern Be it known that l, WILLIAM W. ll rnrn, a citizen of the United States, residingat Kolin, in the county of Judith Basin, State of Montana, have invented certain new and useful lmprovements in Plows or Cultiva tors; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to plow or cultivator structures, particularly to implements employing rotary cutters, and aims primarily to provide means of a simplified and improved nature whereby the cutters may be securely attached to the cultivator frame and so held during operation; the construction permitting of various adjustments of the cutters so that the angularit or inclination of the same relative to the ground may be varied. i

A further object of the invention is to provide means whereby circular cutters in any desired number may be arranged upon the cultivator frame, and the said cutters or blades disposed either in a common angle or inclination or at various angles, accordin? as conditions may require.

ratillfurther objects reside in an improved mounting for the cutters, improved means for securing the disk shaft in angular position, and improved staying means for the cutters. 1

These objects, as well as others which will appear as the description proceeds, are

accomplished by means of the preferred practical example of cultivator mounting illustrated in the accompanying drawings and described in the annexed specification, but it will be understood that variations in. the construction, details and arrangements of partsmay be resorted to without departing from the invention as defined by the claims.

in the drawings:

Figure 1 is a plan view of a cultivator oi conventional construction, showing the use of circular cutters in the manner con-' templated by the invention,

Figure 2 is a fragmentary side viewfiof one of the frame bars with a cutter attached, Figure 3 1s a sectional View through supporting bracket and block, on, theline 3 8 of l 1gure2,

ofthe machine showing one'of the rear wheel supports.

The cultivator illustrated in the accompanying drawings comprises two parallel longitudinal or side bars 5, connected adjacent their forward ends by the cross bar 6, and having at their rear ends the divergent bars 7. The rear ends of the innermost of the divergent bars rest upon the lateral member 8, on which the rear draft wheels 9 are mounted 1 by means of the crank axles 9. Mounted on the inner face at the forward end of each of the side members 5 is a vertical channelledsupport 10, and slidable vertically ineach member 10 is a plate or bar 11. Secured to each bar 11 is a right angularly extending bracket 12 on which is pivotally mounted the knuckle 13. This knuckle carries the stub axle lt, which rotatably supports the ground ensteering wheels 15. lilxtending forwardly from each knuckle is an arm 16, and ext-ending transversely of the machine, and pivotally connected at its ends to the arms 16, is the steering rod 17. The intermediate portion of'the rod 17 is pivotally connected to the draft tongue 18, which tongue is pivotally secured to the bar 6. As the draft tongue is swung from side to side, the roc will be moved to steer the wheels 15. Draft animals or a tractor may be attached to the draft tongue 18. Mounted on each of the inner bars 7 is an adjusting lever 19, and connected to each lever,

straight throughout its entire length, having a right angularly disposed footf22 at one end which [is adapted to rest upon the 2 ll., i-30,608

flat faces of the frame bars of the cultirator. The bracket is also preferablv pro: vided with reinforcing webs 23, a ged at the longitudinal edges of the bracket and connecting the foot with the body portion thereof. The foot is provided with an opening adapted to align with any of the openings 24, arranged at intervals through out the length of the longitudinal bars 5 of the frame, as well as the divergent bars 7 thereof. Bolts 18 passed through the alignedopenings will maintain the bracket in rigid position, on the bar 7.

The outer extremity of the bracket is rounded as shown, providing what may be termed a circular plate portion 25, through the center of which an opening is made. The forward face of this plate is provided with radial teeth 26 adaptedto interlock with similar teeth 27 on the plate portion 28 at the inner end of the block or head 29. The plate portion 28 of the head is provided with an opening through which a retaining bolt 30 is passed; it being understood that when the bolt ispassed through the aligned openings of plates 25 and 28 and the head 29, and they nuts thereon tightened, the teeth 26 and 27 will be interlocked and the head or block 28-will be positively held against r0- tation upon the bracket. Should it be desired to vary the angularity of the block 28, it is but necessary to loosen the nuts upon the bolt 30, whereupon these adjustments may be easily and conveniently made. 1 Block 28ris provided with an opening 31 passing transversely through the block, and adapted to receive the shaft 32 which supports the circular, cutter disk 33. A set screw 34: threaded into the block and into the -opening 31 thereof will hold the shaft against longitudinal or rotary movement within the said opening.

Any preferred means may be employed for rotatably mounting the cultivator disk 33 upon its supporting shaft 32. However, in the present instance, the disk has a central aperture through which the shaft 32 extends, said shaft also passing through an elongated collar or sleeve 35 affixed to the rear face of the disk andconstituting a bearing for the latter. The shaft is maintained against longitudinal movement by means of the pin 36 confined between the rear face of the outer disk and within the socket 35 at the inner end ofsleeve 85.

To assist the bracket andhead in bearing the strain to which. the blades must be sul jected, stays 37 are provided. These stays may be constructed of rod iron provided at one end with eyes 38 to, engage around the shaft, the opposite ends of the stays being threaded to receive clamping nuts 39. One of the staysj is provided with a relatively small? eye toencircle the reduced threaded end, of: the .diskshaft32, and jamb nuts 38.

dispo ed one upon each side of the said eye will firmly hold the stay in proper position. The outer ends of the stays 37 pass through openings arranged respectively in the outer ends of the bracket elO and in the frame bars 5 and 7 of the cultivator.

Mounted on the upper end of each of the channel members 10 is a rock segment 41, and pivotally carried by this segment is a lifting and lowering lever 42, said lever having an angularly extending foot d3, which is pivotally connected with the bar 11 by means of the link 44-. I

lVith the cultivator constructed in accordance with the foregoing, it is apparent that the cutting blades may be arranged in close relation or far apart as desired, and the angularity of these blades with respect to vertical as well as horizontal planes may be accurately governed. In providing the stays 37 for the opposing ends of the blade shafts, it is apparent that the strains will not alonebe borne by the supporting bracket, but will be equallydistributed as well to the said stays. The stays, furthermore, assist in maintainingthe rigidity of the disks.

Also, the disks and shafts may be swung over to the opposite sides of the frame bars 5 and 7, as the case'may require, as when employing the machine for, shallow cultivation.

What is claimed is:

1. In acultivator attachment, a bracket, a feet at one end of said bracket adapted to be secured to the frame of the cultivator, a block adjustably mounted at the outer end of said bracket, the said block having an opening therein, a cutter shaft extending through said opening and adjustable therein and means for holding the said shaft in adjusted positions.

2. In a cultivator attachment, a bracket, a foot at one end of said bracket adapted to be secured to the frame of the cultivator, a block adjustably mounted at the outer end of said bracket, the said block having an opening therein, a cutter shaft extending through said opening and adjustable therein, means for holding the said shaft in adjusted positions, and stays connecting said shaft to the cultivator frame.

3. In a cultivator attachment, a bracket, a block carried by the bracket and adjustable thereon, a shaft carried by the block, a

cutter disk having an opening therein, one

end of the shaft being reduced and threaded. and extended through said opening, a sleeve on said disk enclosing a part of said shaft, a pin extending through said shaft between the cutter disk and the sleeve, and stays carried by said shaft. Y

4. In a device of the class described, a circular cutter, a shaft for said cutter, a

bracket supporting said shaft in adjusted positions, stays for said shaft comprising In testimony whereof, I aflix my signature 1n the presence of two Witnesses.
